This is an automated bandwidth throttler that runs on high end routers flashed with dd-wrt builds that include perl. It calculates the bandwidth allotted in a billing cycle, how much bandwidth has been used cycle to date and throttles the downstream to attempt to stay below your ISPs bandwidth cap. Calculations are made using the combined upstream and downstream but throttling is done using downstream only for performance purposes. As such, this utility is not meant for for people whose upstream represents a large portion of their traffic. In time, a version that runs on a client machine and accesses the router over SSH or telnet is planned.
